CORC® cables and wires form our solution for power cable needs in liquid nitrogen or pressurized helium gas:
– The highest operating currents and current densities available
– The best performing Fault Current Limiting solution available

CORC® power and Fault Current Limiting cables and wires are being developed with support of the U.S. Navy and in collaboration with the Center for Advanced Power Systems at Florida State University.
